You also asked about using your friend's Nikon 3200. Altough I don't know the camera, it appears that in the "Fine"quality setting can produce 10 MB pictures. This would be about 2000 x 1500 pixels, and good enough for a good enlargement. It means, of course, that you would have to retake the picture with that camera and using its "Fine" setting.
The max resolution on the D3200 is actually a whopping 6,016 × 4,000 pixels.
